Size and form in efficient transportation networks

Article Abstract:

It has been possible to establish a general relationship between size and flow rates in arbitrary transportation networks with local connectivity. This theory can be applied easily to the problem of allometric scaling in living organisms, which span size scales ranging over many orders of magnitude. A variety of biological quantities (generically characterized as Y) that are connected to blood circulation scale algebraically with the mass M of the organism. This research should be applicable to a wide range of distributed networks.

Scour in large braided rivers and the recognition of sequence stratigraphic boundaries

Article Abstract:

A study conducted in the Jamuna River of Bangladesh shows the alluvial scour created by a river that shifts to a new base level after a corresponding decline in the sea level. Channel confluences and bends are found to create scours that are five times deeper than the mean depth of the river. These effects can be used to evaluate ancient scours using variations in base level and climate.

Rivers, blood and transportation networks

Article Abstract:

The theory developed by Banavar et al to explain Kleiber's law governing the metabolic rate of mammals is discussed. The metabolic scaling theory focuses on the nutrient distribution network formed by capillaries and arteries.
